This allows computers with a small amount of memory or overloaded system
|
|
to succeed in making the databases for SWIM::DB_Init. Instead of using
|
|
transfer.deb to grab everything into memory and then creating the
|
|
long.debian and big.debian files right out of memory for processing by
|
|
SWIM::MD, it works like longswim by creating one large file to the disk
|
|
(this can use lots of memory, but can swap easily) then it uses slowswim
|
|
to create long.debian and big.debian using a minimal memory method, then
|
|
it finishes using SWIM::MD.
|
|
|
|
To test supply these arguments - info dir, temporary dir "imswim
|
|
/var/lib/dpkg/info /tmp" and create a transfer.deb file
|
|
beforehand in the temporary dir which has the packagename_version one to a
|
|
line.
